Hello,

(a+b) (a-b) = a² - b²

or  a² - b² = (a+b) (a-b)

Step-by-step explanation:

3 ( (x+4)² - 9 ) = 3 ( (x+4)² - 3² ) = 3 (x+4+3) (x+4-3) = 3 (x+7) (x+1)

- (x+9)² + 1 = - ( (x+9)² - 1²) = - (x+9+1) (x+9-1) = - (x+10) (x+8)

Red one !!! answer it pleasee
stealth61 [152]

Answer:

(6, -2)

Step-by-step explanation:

The midpoint of the segment RS is point M (5, 3). Therefore, the average of the x coordinates of R and S is 5, and the average of the y coordinates of R and S is 3. The x coordinate of R is 4. For 4 and the x coordinate of S to have an average of 5, the x coordinate of S must be 6. Therefore, our point is of the form (6, y). For 8 and the y coordinate of S to have an average of 3, the y coordinate of S must be -2. Therefore, our answer is (6, -2)

A. .x=8<br> f(x)=1*1<br> (8) = ?
Ksenya-84 [330]

You are missing information.

f(x) needs to equal an equation that has an x in it.

f(x) = 1 * 1

x = 8

There is nowhere to fill in the 8.

Sorry. :(

What is the answer please
allochka39001 [22]

Answer:

y=(1/2)x+0.5

Step-by-step explanation:

The explanation is quite simple. The standard form is y=mx+b; b is the initial point where the line crosses the y-axis and the m is the slope. From the graph, we see it crosses the y-axis at (0,0.5). The 0.5 is the b. The m is by looking at the rise/run.
